Answer 1

If your app is already installed in your device and your device debuging is already enabled.

Then uninstall the previous app and install the fresh apk

sudo ionic cordova run android

Answer 2

Once you've enabled your device for debugging, make sure to turn on usb tethering on the device;

Settings > Tethering & Networks > USB tethering

This fixed the problem for me.

Answer 3

I had another developer tool opened (Chrome Inspect) and it "ate" the connection. In my case, just closing the Chrome Inspect panel and running ionic run android worked.

Answer 4

In my case I had Android 5.1.1, and below are the steps I took:

• Please check that your PC recognizes your phone (you can access the files like in a USB flash drive). If not please install the drivers from google here.
• Please check that the USB debugging options is checked on your phone, then: 1- Go to Setting -> General -> '{} Developer options' 2- Look for the 'USB debugging' option 3- If the 'USB debugging' option is disabled then turn off 'Developer options' and turn it back on. Now you should be able to check the 'USB debugging' option.

Answer 5

I solved the problem.

Here is what I did: I typed into the command line: adb devices (located in the "platform-tools" folder in the Android SDK) which returned me an empty list.

So I installed my phone's drivers, which I downloaded from the vendors homepage.

Now the list contains my device and the app is started on my mobile phone.

Answer 6

I had a different problem, with a very simple solution.
When plugging in your Android device for the first time, it'll ask you to trust the computer's certificate. That popup screen disappeared on me, as I was just getting a call.

Simply unplugging/replugging your phone and accepting your computer's certificate should do the trick!
